Summary
This dam stands at a height of 20 feet with a hydraulic height of 17 feet, serving as a critical infrastructure to protect the surrounding area from potential flooding events. With a storage capacity of 165 acre-feet, Celsor Jl plays a vital role in managing water resources in the region.
Maintained and regulated by the Oklahoma Water Resources Board, Celsor Jl has a low hazard potential and has not been rated for its condition assessment. Despite being last inspected in 2006, the dam is equipped with a controlled spillway and a single valve outlet gate for efficient water flow management. The risk assessment for Celsor Jl indicates a very high risk level, emphasizing the importance of regular inspections and maintenance to ensure the safety and integrity of the dam for both flood risk reduction and water resource management in the area.
As a key component of the flood risk reduction infrastructure in Sentinel, Oklahoma, Celsor Jl serves as a critical line of defense against potential flooding events in the region. With its earth construction and stone core design, this dam provides essential water storage capacity and flood control measures, highlighting its significance for climate and water resource enthusiasts who are passionate about sustainable water management practices.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
